A "Kirikaku Inn" exists between reality and other worlds. It forcibly inhales a group of "guests" every day. They need to complete the "Guest Rules" tasks issued by the shopkeeper, and the "shopkeeper" replenishes and condenses grievances;
The inn is actually an aggregation of the resentment of the ancient dead. Guests need to rescue the undead by deciphering the real events behind the code. The losers will become the new puppets of the inn.
